Peter Thomas Roth makes great facial products. This serum has a great smell and texture and I felt like it gave great results without leaving your skin filmy or oily like some serums.

This vitamin c serum has a really nice texture and I enjoy using it, however I think that results have been somewhat hard to pinpoint. It doesn’t do any pilling or weird layering things, but progress is slow. [This review was collected as part of a promotion.]

So far, so good. I finished a bottle of the Skinceuticals CE Ferulic that everyone raves about and while my skin looked brighter, there were two small sun spots that were unchanged. I saw a YouTube video about the different forms of Vitamin C and thought I'd give the PTR Potent C a try since it contains the Tetrahexyl version of Vit C (the Skinceuticals contains L-ascorbic acid). I find the PTR easier to use since it's just a pump bottle and the formula sinks right into my skin and isn't tacky. That right there is an improvement over the Skinceuticals. I have noticed a very slight improvement on the sunspots and it's been two months of use. So, no miracles here yet, but I will continue to use and would consider repurchasing

Very good vitamin C serum! On the expensive side and not sure if the effects were worth the price, so trying other vitamin C serums out before repurchase.

I used the entire bottle and haven’t noticed a long term difference. Although right after I put it on it does soften the skin and hydrate. [This review was collected as part of a promotion.]

First time user of this ...This product feels great on your skin but I didn’t really see any long term improvements in my skin.

Absolutely OBSESSED with this serum! I purchased it on my own, after a recommendation from an employee at Sephora. I went through an entire bottle and was thrilled with the results, and am excited to see the continued results as I further treatment. My skin is acne prone and has a ton of scars (I just started the spot brightening treatment) and will update my review after month 2.

Peter Thomas Roth is a great product and I was very surprised on how satisfied I was with this serum. The product is expensive but it lasts a long time and leaves the skin feeling refreshed and I could tell a difference after about a week.
